Classify each process as spontaneous or nonspontaneous. 1) water is separated into h_2 and o_2 gas at 25 degree 2). a cup of hot coffee cools to room temperature. 3) the extraction of iron metal from iron ore. 4) perfume molecules spread out to fill the entire room. 5) iron rusts in moist air.

If the same amount of cacl2 is added to equal volumes of water and maple syrup, which will have the higher temperature?

In most resting cells, the concentration of sodium ions is higher outside of cells compared with the intracellular fluid. when cells are stimulated, sodium ion channels open, and sodium diffuses from the outside of the cell to the inside of the cell. sodium ion concentrations in a resting cell are an example of and sodium ion movement in a stimulated cell is an example of in most resting cells, the concentration of sodium ions is higher outside of cells compared with the intracellular fluid. when cells are stimulated, sodium ion channels open, and sodium diffuses from the outside of the cell to the inside of the cell. sodium ion concentrations in a resting cell are an example of and sodium ion movement in a stimulated cell is an example of potential energy; kinetic energy kinetic energy; potential energy the energy of motion; stored energy chemical work; energy stored in chemical bonds
